Identification of coptis chinensis
1, character recognition
Roots are clustered and branched, curved and clasped, shaped like inverted chicken feet, commonly known as chicken feet Coptis chinensis; Single branch is cylindrical, 3 ~ 6 cm long and 2 ~ 8 mm in diameter. The surface is grayish yellow or yellowish brown, the peeling part of epidermis is reddish brown and rough, with irregular nodular uplift, fibrous roots and fibrous roots residues, and some internode surfaces are smooth as stems, commonly known as crossing the bridge; There are many brown scales in the upper part, and there are often residual stems or petioles at the top. Hard texture, irregular section, orange-red or dark brown peel, bright yellow or orange-yellow wood, reddish brown pith, and sometimes hollow. A slight breath, an extremely bitter taste. [2]
2. Microscopic identification
Cross section of rhizome:
Scales often fall off. Cork layer is a series of cork cells. The cortex is broad, and some can see the vascular bundles of root trace and leaf trace; Stone cells are yellow and scattered individually or in groups. The paper bundles are tough outside, arranged in intermittent rings, and the formation layer between bundles is not obvious. There are fiber bundles on the outside of phloem, ranging in size from a few to dozens or hundreds; Some are accompanied by yellow stone cells. The xylem is yellow and lignified; Wood fiber is relatively developed. Sometimes some single or group stone cells can be seen between parenchyma cells of pulp. Thin-walled cells all contain starch granules. [2]
3. Powder characteristics
Tan or yellow.
① The stone cells are bright yellow, round, square, polygonal or slightly slender, with a diameter of 25-64? M, about 102? M, wall thickness 9~28? M, the pits are obvious, and some levels are obvious.
② There are many woody fibers, yellow and slender; Diameter 10~ 13ctn, slightly thick wall, lignified and sparse pits.
③ The phloem fiber is bright yellow, spindle-shaped or long-spindle-shaped, and its length is 136~ 185? M, diameter 25~40? M, the wall is thicker and the pit is thinner.
④ Catheters are mainly perforated and threaded, with a diameter of 8-20? m .
⑤ Most starch granules are single, rectangular, kidney-shaped, spherical or oval, with a diameter of 1~ 10? m； There are a few composite particles, which are composed of 2~4 fractions. The epidermal cells of scales are yellow-green or yellow-brown, slightly rectangular, and the walls are curved like microwaves.
